    ABSTRACT: Primary hepatic leiomyoma is a neoplasm of mesenchymal origin and occurs only rarely. Secondary to benign smooth muscle proliferation, it is usually found in adult women and is associated with Epstein-Barr virus (EBV) infection. Here, we report the 29(th) case of primary hepatic leiomyoma with its unique features related to diagnosis, treatment and developmental biology. A 48-year-old man, with an immunocompromised status, complained of pain in the upper quadrant of the abdomen. Serological analysis indicated no presence of hepatitis virus, no human immunodeficiency virus, and no EBV infection. The levels of α-fetoprotein and carcinoembryonic antigen were normal. A mass was detected in segment III of the hepatic lobe by ultrasonography and an abdominal computed tomography scan. Endoscopy had negative findings. Exploratory laparotomy found no existing extrahepatic tumor and left lateral lobectomy was performed. Pathological examination showed the mass to be a typical leiomyoma. The cells were positive for α-smooth muscle actin and desmin, and negative for the makers of gastrointestinal stromal tumor (GIST), including CD117, CD34 and DOG1 (discovered on GIST1). In situ hybridization revealed negative status for EBV-encoded small RNA. After left lateral lobectomy, the patient was not given chemotherapy or radiotherapy. During a 2-year follow-up, no sign of local recurrence or distant metastasis was observed. In conclusion, we report a rare case of primary hepatic leiomyoma in a male patient without EBV infection. Hepatic resection was curative. This case presents data to expand our knowledge concerning the complex and heterogeneous nature of primary liver leiomyoma, indicating that EBV infection is important but neither necessary nor sufficient for the development of primary liver leiomyoma.

    ABSTRACT: To observe the histopathological features of posttransplant complications for hepatic allografts and evaluate their biopsy values. From January 1999 to May 2011, a total of 268 percutaneous hepatic allograft biopsies were conducted in 207 recipients and the diagnostic procedures for staining, classification and staging performed according to the Banff schema and Chinese Schema on hepatic allograft rejection. Among them, there were ischemia/reperfusion injury (n = 26, 9.7%), acute T cell-mediated rejection (n = 83, 31.0%), acute antibody-mediated rejection (n = 12, 4.5%), chronic posttransplantation rejection (n = 31, 11.6%), immunosuppressive-induced liver injury (n = 70, 26.1%) and recurrent diseases (n = 18, 6.7%). Acute T cell-mediated rejection and drug-induced liver injury were two most common causes of allograft dysfunctions. Percutaneous hepatic allograft biopsy is valuable for the diagnosis and evaluation of various posttransplantation complications.

    ABSTRACT: Living donor kidney transplantation (LKT) has been booming in China. This study aimed to elucidate the renal function of both Chinese donors and recipients after the donation and transplantation. One hundred and forty-one pairs of donors and recipients for LKT were randomly selected and followed up for up to seven years. The donors' and recipients' renal function was recorded before and after operation. The donors presented a mean age of (43.9 ± 7.5) years at donation. The female contributed 101/141 (71.6%) in all donors, and no effect was shown between genders on healthy donors' renal function. The donors' glomerular filtration rates (GFR) were (119.5 ± 20.4) ml/min, (85.2 ± 17.6) ml/min, (87.2 ± 15.9) ml/min, (82.1 ± 14.6) ml/min and (83.0 ± 13.7) ml/min preoperatively, and for five days, three months, one year and beyond one year after the operation. The donors for the period of 1 - 3 years, 3 - 5 years and more than 5 years after donation showed GFR as (83.9 ± 12.7) ml/min, (83.0 ± 17.6) ml/min, and (80.9 ± 20.8) ml/min, respectively, no statistically significant difference was found. Moreover, no significant clinical changes in blood pressure and proteinuria were found among the donors. In the recipients, delayed graft function (DGF) rate was 6.4%, acute rejection rate was 11.3%, and GFR were (66.5 ± 16.4) ml/min, (73.2 ± 19.6) ml/min and (63.9 ± 18.6) ml/min respectively at three months, one year and beyond one year post-transplantation respectively. The donors/recipients of LKT in Chinese population experience well-functioning remaining/donor kidneys.

    ABSTRACT: To summarize the histopathological features of posttransplant complications for renal allografts and evaluate the biopsy values. Between January 1997 and May 2010, a total of 1712 percutaneous renal allograft biopsies were performed in 1500 kidney transplants and diagnostic procedures for staining, classification and staging had been performed according to the Banff 1997 and 2005 Schema. There were 213 (14.2%) cases of acute T cell-mediated rejection post transplantation in 1500 kidney transplants. Meanwhile there were 36 (2.4%) cases of acute antibody-mediated rejection. Chronic T cell-mediated rejection and chronic antibody-mediated rejection were 251 (16.7%) cases and 45 (3.0%) cases, respectively. Acute CNI-nephrotoxicity and chronic CNI-nephrotoxicity were 106 (7.1%)cases and 251 (16.7%) cases, respectively. Relapsed or new nephropathy were 6 (0.4%) cases. Chronic CNI-nephrotoxicity is the most common cause of allograft dysfunction in the long survival recipients. Percutaneous renal allograft biopsy is valuable for the diagnosis of various posttransplantation complications.

    ABSTRACT: 20 ml peritoneal lavage fluid of mice infected with Toxoplasma gondii RH strain was diluted to 250 ml with sterilized physiological saline, and filtered through cellulose membrane filters (pore size: 5 microm). The filtrate was centrifuged at 1512 x g for 15 min, and the sediment was pure T. gondii tachyzoites which were then sonicated. The soluble antigen was prepared by centrifugation at 11200 x g for 30 min. Sera of T. gondii infected SD rat and normal SD rats were collected for immunodetection of soluble antigen. The specificity and valence of soluble antigen were detected with indirect ELISA. The mean removal rates of mouse leukocytes and erythrocytes were 99.9% and 80.3%, respectively, and recovery rate of tachyzoites was 71%. The soluble antigen was extracted from purified T. gondii (1.38 mg per mouse). Indirect ELISA showed that the lowest effective antigen concentration was 5 microg/ml.

    ABSTRACT: Combined en bloc liver/pancreas transplantation (CLPT) was used primarily in the treatment of otherwise non-resectable upper abdominal malignancy. In fact, a more appropriate indication is in patients with liver disease and insulin-dependent diabetes mellitus (IDDM). Here, we report on two successful cases of CLPT at our hospital. One was a patient with non-resectable advanced liver cancer. The recipient survived for 23 mo and finally died of recurrent tumor. The other was a patient with severe biliary complication after orthotopic liver transplantation and preoperative IDDM. We performed CLPT with a modified surgical technique of preserving the native pancreas. He is currently liver-disease- and insulin-free more than 27 mo post-transplant. Based on our experience in two cases of abdominal cluster transplantation, we describe the technical details of CLPT and a modification of the surgical procedure.

    ABSTRACT: To report the modified technique and the short-term results of simultaneous pancreas-kidney transplantation (SPK) with the enteric drainage (ED) of exocrine secretions. From June 2000 to August 2006, thirty-eight patients with diabetes complicated with uremia underwent SPK. The pancreas graft was placed intraperitoneally with exocrine secretions drained into the proximal jejunum without Roux-en-Y procedure. The mean cold ischemic times of pancreas and kidney were (10 +/- 2.0) h and (7 +/- 2.0) h, respectively. Quadruple immunosuppressive therapy with antilymphocyte globulin or anti-CD25 monoclonal antibody, tacrolimus, mycophenolate mofetil and steroids was adopted except one patient. The 6-month survival rates of patients and grafts were both 97.4% after transplantation. All patients achieved insulin-free euglycemia at (7 +/- 6.9) d postoperative except one. For preoperative patients, mean fasting insulin and C-peptide values were (9 +/- 8.1) mU/L and (6 +/- 4.5) mU/L. After operation, fasting insulin and C-peptide values of patients were (12 +/- 5.8) mU/L and (6 +/- 4.7) mU/L, respectively, which peaked to an insulin level of (57 +/- 43.0) mU/L and a C-peptide level of (11 +/- 6.8) mU/L with stimulation. There were eight cases of delayed renal graft function. All other patients achieved immediate renal graft function. No graft losses occurred due to leakage or intra-abdominal infection. The most common surgical complications were wound infection (n = 12), enteric anastomostic hemorrhage (n = 5) and perirenal hemorrhage (n = 2). Three patients (7.9%) had been reoperated for the reasons of intra-abdominal hemorrhage and perirenal hemorrhage. SPK is an effective treatment option for selected patients with diabetes mellitus and approaching end-stage renal disease. Enteric exocrine drainage by direct side-to-side anastomosis (without Roux-en-Y) seems to be a simple and reliable technique.

    ABSTRACT: Biliary complications continue to be an important determinant of the recipient's survival rate after orthotopic liver transplantation (OLT). The objective of this study was to evaluate the incidence of early biliary complications in OLT in the presence or absence of a T-tube. This retrospective study, based on inpatient data, focused on the relationship between T-tube placement and early biliary complications of 84 patients after OLT, from November 2002 to June 2005. Patients were divided into two groups based on whether or not a T-tube was used following bile duct reconstruction: T-tube group (group I, n = 33); non-T-tube group (group II, n = 51). 45.2% of OLT recipients had a malignant neoplasm. There were no significant differences in the demographic characteristics or operation data between the two groups. Overall, early biliary tract complications developed in 19.0% (16/84) of patients. The rate of early biliary complications was 30.3% (10/33) and 11.8% (6/51) in groups I II, respectively (p = 0.035). Biliary complications which were directly caused by T-tube placement occurred in 12.1% (4/33) of patients in group I. Overall, the percentage of malignant neoplasms, chronic viral cirrhosis, fulminant liver failure and other primary disease recipients with early biliary complications were 6.2%, 37.5%, 43.8% and 12.5%, respectively. This study suggests that the use of a T-tube in Chinese patients undergoing OLT causes a higher incidence of early biliary complications. Most of the early biliary complications occurred in chronic viral cirrhosis and fulminant liver failure recipients.

    ABSTRACT: Pancreas transplantation (PT) has proved effective but it is associated with a high risk of surgical complications and technical failure. Duct management and venous drainage are identified as major issues. Improvements in immunosuppression and prophylaxis greatly have contributed to surgical progress. A literature search of the PubMed database (1996-2005) was conducted and research articles on PT reviewed. More than 23 000 PTs have been performed throughout the world. The majority (83%) were performed in combination with kidney transplantation [simultaneous pancreas-kidney transplantation (SPK)]. Pancreas graft survival rates at one year were 85% for 2001-2003 SPK cases, 79% for pancreas after kidney transplantation (PAK) cases, and 76% for pancreas transplantation alone (PTA) cases. For the 1999-2003 cases, enteric drainage was done in 79% of the SPK cases and bladder drainage in 21%. Patient survival rates, pancreas and kidney graft survival rates, and pancreas graft immunological failure rates did not differ significantly in enteric versus bladder drainage cases. All the available data fail to demonstrate a definitive advantage of portal drainage over systemic drainage. From 1993 to 2002, the use of rabbit antithymocyte globulin increased from 0 to 37%; the use of daclizumab increased from 0 to 16%; and the use of basiliximab increased from 0 to 25%. In 1993, 98% of SPK recipients received cyclosporine; but this was decreased to 9% in 2002. Tacrolimus (FK506) usage has increased from 0 (1993) to 87% (2002) of SPK recipients. Sirolimus (SIR) usage has increased from 0 (1993) to 18% (2002) of SPK recipients. PT remains an effective therapy for treatment of type I diabetes mellitus. Enteric drainage is currently predominant in SPK, but bladder drainage is still largely used. Portal drainage is as safe as systemic drainage, but there is still no convincing evidence about whether it is immunologically or metabolically convenient. The combined of FK506 and mycophenolate mophetil (MMF) is the preferred maintenance immunosuppression in PT. Sirolimus may be a good alternative as a second agent in recipients of PT under FK506 therapy.

    ABSTRACT: As a valid therapeutic option for patients with type 1 diabetes mellitus (IDDM) and secondary diabetic nephropathy, simultaneous pancreas-kidney transplantation (SPK) remains more undeveloped than other solid organ transplantations due to the restrictions of surgical techniques especially the modes of exocrine pancreatic secretion. The aim of this paper was to summarize our single-center experience in SPK with modified enteric drainage (ED). From June 2000 to July 2003, 10 patients with IDDM associated with uremia received SPK. The pancreatic allograft exocrine secretion was drained into the proximal jejunum via a side-to-side duodenojejunostomy without Roux-en-Y anastomosis. Quadruple immunosuppressive regimen consisted of induction of tacrolimus (TAC)/cyclosporine (CsA), mycophenolate mofetil (MMF), steroids and antibodies, which included antilymphocyte globulin (ALG) or anti-CD25 monoclonal antibody. ED-SPK without Roux-en-Y anastomosis was successful in all 10 patients without serious complications such as pancreatitis, graft thrombosis and pancreatic fistula. The patients regained immediate kidney allograft function and euglycemia with insulin-independence. Four patients survived over one year. Episodes of acute rejection were observed in 4 patients, 3 of whom showed reversion after treatment of OKT3 or insulin. Early postoperative complications included peritoneal infection (2 patients), wound infection (2) and renal hematoma (1). ED-SPK without Roux-en-Y anastomosis is safe and preferable to the patients with IDDM associated with uremia.
